OR2J3 Gene

The OR2J3 gene encodes a particular olfactory receptor, a protein that reacts
to specific molecules in the nose to trigger a signal in our perception of
smell. OR2J3 encodes one of hundreds of different types of olfactory receptors
in the nose. Leaf alcohol (cis-3-hexen-1-ol) — and other chemicals similar to
it — trigger the receptor encoded by OR7D4.

Alleles

People normally have two alleles per gene,
one inherited from their mother and one inherited from their father.

Sensitive
(Global)

This allele has been widespread globally for tens of thousands of years.

Insensitive
(African)

This allele originates from an ancient African mutation
that occurred thousands of years ago.

Allele Pairs

It is the combination of a person's pair of gene alleles that influences traits.
